Title: Shutting down oil well blowouts - using remote controlled bore drill in underground shaft beneath well head to pump pressure countering materials into oil pipe
Inventor: POSCH HARALD
IPC: E21B33/068
Filed: 1991-05-02
Abstract: Shutting off oil well blowouts, partic. when the well is on fire and the oil is under great pressure, by closing bore pipes with at least one casing and one inner tube. The combined use of remotely controlled blow out preventer to clamp shut the bore tubes, and a core drill through which slurry can be pumped to counter the well pressure is new. Access to the underground bore pipe is by digging a shaft and gallery. Inductive heating of the pipe assists the blow out preventer to clamp shut the pipe. Downstream of the clamped section, a pressure tight sleeve is clamped around the pipe casing. Shims and seals allow for surface irregularities. Flanges on the sleeve allow attachment of a remotely driven and controlled drill. The bore drill enables an injection of material into the casing and tube gaps to give a pressure seal. Through a ball valve, a high pressure pump at the surface, pumps high density slurry into the oil pipe to equalise the oil well pressure. ADVANTAGE - Allows blow outs to be stopped under controlled conditoins without danger of fluid pressure shock waves. Remote controlled operation minimises danger to personnel.

Title: Carbonate mineral calcination - has an air-free deacidification zone between firing and cooling zones
Inventor: HOELTJE WILLI
IPC: C04B2/10
Filed: 1991-05-14
Abstract: To calcinate fragments or granules of limestone, dolomite or similar carbonate minerals, a subsequent deacidification zone (C) with no air passing through is between the firing zone (B) and the cooling zone (C) with no air passing through is between the firing zone (B) and the cooling zone (D). The kiln pressure is adjusted at the hot air extraction so that the underpressure at the kiln outlet of the hot gas extn. equals the underpressure in the lower firing zone (B). Pref., the air required for calcination is controlled by a fan (6) fed in over each material removal lock (5) at the lower section of the cooling zone (D). It is drawn out from the upper section of the cooling zone (D) by a fan (7) and passed with a fuel for the burners (8,9) into the firing zones (2,3). Sec. combustion air is passed over the burners (8,9) through openings (12,13). Surplus air, not requiring for firing, is passed by the deacidification (C) and firing (B) zones in the same direction as the material being processed. Part of the combustion gas in the lower firing zone (B) is moved with the material to pass it through. The hot air extn. at the start of the cooling zone (D) operates alternately to the kiln or to give a threshold temp. in a time cycle of 10-30 mins. On exceeding a given hot air temp., sufficient fresh air is passed in under control through a control flap (14) to the hot air fans (7) to maintain a constant required temp. The cold air fan (6), hot air fan (7) and exhaust gas fan (17) are controlled. ADVANTAGE - The deacidifying is improved to achieve the required calcinated product quality, with a redn. in the specific heat requirements.

Title: Discharge device for bottle cleaning machine - has cyclic correcting movement to reduce downward speed
Inventor: GROT UWE
IPC: B08B9/44
Filed: 1991-05-29
Abstract: The bottles are moved standing above the delivery table on a chute from baskets over the edge of the chute and are taken up by fingers (6) which are moved by a simple lever mechanism driven by a rotary main drive with a sinusoidal downward speed to below the delivery table. This downward speed is reduced level with the delivery table at a suitable point (38) of the lever mechanism. The fingers (6) are mounted on the drive lever (17') to swivel with the correcting movement about a swivel axis (38) which is parallel to the edge (5) of the chute (4). The correcting movement is  pref. produced by a curved path (41). USE/ADVANTAGE - Since the correcting movement is cyclic the lost time can be made up with a higher speed at another point so that the fingers remain synchronous with the remaining path of movement of the machine.
